Multiple spraying gun devices used for dryer

The invention provides multiple spraying gun devices used for a dryer. The multiple spraying gun devices comprise at least three spraying device sets, connecting blocks, handles, hinged bolts, sliding blocks and sliding block bases. The spraying gun devices are evenly distributed, the included angle formed by the two axes of every two adjacent spraying gun devices is smaller than or equal to 120 degrees, and each spraying gun device set comprises a spraying gun, a guiding tube and a spraying gun cover. The upper portions of the spraying guns are sleeved with the coaxial guiding tubes, the spraying gun covers are arranged on the lower portions of the spraying guns, the sliding block bases are arranged on the spraying gun covers, the sliding blocks are fixed to the sliding block bases and connected with the guiding tubes through the connecting blocks which are further connected with the handles, and the handles are connected with the spraying gun covers through the hinged bolts. The angle of the spraying guns can be adjusted, in this way, low-agglomeration granulation and high-agglomeration granulation are achieved, and the purpose of adjusting the product granularity is achieved; meanwhile, the multiple sets of spraying guns are erected on the same drying tower for working at the same time, in this way, the amount of treated slurry is increased, and the yield is also increased.
